A day before the Pennsylvania Democratic primary, it appears Hillary Rodham Clinton will fend off a late charge from Barack Obama, the latest SurveyUSA poll found.

The poll, the fifth conducted exclusively for NBC 10 and several other local television stations throughout the state, concluded that women will carry Clinton to victory, despite a surge for Obama in the southeast portion of the state.

According to the survey, Clinton will carry the symbolically important popular vote, but not by enough to gain material advantage in pledged delegates, according to the final SurveyUSA tracking poll for the primary.

The survey concluded that Clinton will finish with 50 percent, 6 percentage points ahead of Obama. The margin of sampling error is 3.8 percent.

Looking only at SurveyUSA numbers and ignoring the polls that have been released by 12 competing pollsters in Pennsylvania, Obama gained ground in a week when he was largely on defense and off-message. Last week, SurveyUSA had Clinton ahead by 14 points. Monday, in a poll conducted using the identical methodology, SurveyUSA found Clinton ahead by 6 points.

A large shift of support occurred in the Philadelphia area and other parts of Southeast Pennsylvania, which includes most of the state's African-American population. The poll found that Obama finished strongly, ahead of Clinton by 14 points within that demographic.

Among liberals, Obama began 18 points behind Clinton but finished 11 points ahead of Clinton. Among those who have not graduated from college, Clinton led by 28 points last week, but by 15 points Monday.

Among voters under age 50, Clinton had led by 8 points last week and trailed by 8 Monday.

Here's what has not changed: Among women, Clinton has led by 30, 28, 28, 22, and 23 points in five polls. Among voters 50 and older, Clinton has led by 26, 22, 24, 20, and 20 points in the polls.

The pollsters surveyed 1,800 Pennsylvania adults between Friday and Sunday.
